ARRANGEMENT 0F DAMPERS 0F COOKING-STOVES.

Specification of Letters Patent No. 14,720, dated April 22, 1856.

To all whom it may concern:

Be it known that I, WILLIAM E. HAYES, of Geneva, in the county ofOntario and State of New York, have invented certain new and usefulImprovements in the Mode of Constructing Summer-Stoves, of which thefollowing description, illustrated by the accompanying drawings andreferences, is sufficiently clear and comprehensive to enable others ofcompetent skill to make and use my invention.

The nature of my improvement relates to an arrangement for alternatelyopening and closing the air passages within the rectangular flues at thebase of the oven.

Figure 1, is a perspective view of the whole apparatus. Fig. 2, is aperspective view of the flues and dampers at the bottom of the oven,represented as detached from the stove, and Fig. 3, is a verticallongitudinal section of the same.

A is the circular fire box connected by the pipe B to the flue D withinthe sheet iron air chamber or oven C which may assume a variety of formsaccording to the taste of the designer. Within this air chamber the flueD is connected at one end with the flue E, and with a like flue E at theopposite end of the fire chamber, the latter being continued over thetop of the oven and connected with the pipe F, upon the top of thestove.

The mode oficonstructing the flues G, I, H will be understood byreference to Figs. 2 and 3. It is composed of the two outside passages Gand H, and the central passage I which is equal in width to the uprightflues at the ends of the air chamber or oven. The dampers J, K, are hungso that upon being turned up it will close the bottom of the flue E andwhen down will close the passage I.- And the other K hung upon thedamper rod M so that it will close the flue E. To this damper isattached the lever N by a hinge, and passing through are openings at Oas a fulcrum or support and extending under the edge of the damper J sothat upon K being opened J will be thereby closed, and as K is closed Jwill open by its own weight. By means of this arrangement the smoke andheated air from the fire box will pass first through the outer passagesG H and then return through the inner passage I to the flue E when theflue E is closed. And when the flue E is closed it will pass directlyfirst through the inner passage I to the flue E which will then be open,and from thence through the pipe or flue at the top of the oven to thepipe F as before. The regulation or change of position (from the open toclose) of these flues may thus be made by simply turning the damper rodM upon the outside of the air chamber. An import-ant object in thisarrangement is to furnish a stove for summer use for the-purposes ofbaking, warming, and otherwise preparing articles of food, or forheating sad irons, and for other purposes so that a small amount of heatwill be communicated to the air within the room, (the fire box beingusually placed and conoealed within the fire place constructed primarilyin the apartments,) and yet a requisite amount of heat be carriedthrough the passages and flues for the purposes above named, differentportions of which will be more or less heated as the dampers are turnedup or down.

l/Vhat I claim as my invention 'and desire secured to me by LettersPatent is The dampers J, and K connected and operated by the lever N anddamper rod M in the manner and for the purposes specified.

WILLIAM E. HAYES.
